BACKGROUND OF THE INVENTION

This invention relates to sterilization.

SUMMARY OF THE INVENTION

A UV-C generation device is provided that includes multiple UV-C light emitting diodes (“LEDs”) positioned around a work area. For example, the multiple UV-C LEDs may be positioned around a cylinder. The cylinder may be, for example, comprised of a UV-C transparent material (e.g., a material with UV-C transparency greater than fifty percent (50%) such as, for example, quartz or UV-C transparent polymer. The LEDs may be located on a flexible printed circuit board. The flexible printed circuit board may be fabricated, for example, from a polyimide or FR4 and may be, for example between 2 thousandths of an inch and seven thousandths of an inch thick (e.g., between 2 and 4 thousandths of an inch thick such as between 2 and 2.5 thousandths of an inchd thick). A working substance (e.g., a gas, a liquid, an air and liguid) may flow through the cylinder and the UV-C LEDs may interact with the working substance to, for example, sterilize the working substance. The UV-C LEDs may, for example, have a wavelength between 200 and 280 nanometers (e.g., between 220 and 280 nanometers or between 250 and 265 nanometers or between 255 and 260 nanometers such as 255, 260, or 265 nanometers).

Each UV-C LED may be independently controlled and regulated through control and regulation circuitry on the flexible printed circuit board or another device. Accordingly, the intensity of each UV-C LED as well as the turn-ON time and turn-OF time of each UV-C LED may be independently controlled. A processor may be provided on the flexible circuit board or on another communicatively coupled device to control the operation of the UV-C LEDs.

The flexible printed circuit board may be, for example, wrapped around all of, or a portion of, the cylinder so that the UV-C LEDs may provide UV-C light into the cylinder through the cylinder wall. UV-C LEDs may be arranged in rows and columns. A UV-C flexible circuit when wrapped around a cylinder may, for example, have rows of three (3) UV-C LEDs in multiple columns (e.g., three columns, six columns, nine columns, twelve columns, more than twelve columns, or any number of columns). Accordingly, six columns of three UV-C LEDs would provide eighteen UV-C LEDs. The UV-C LEDs may be aligned in rows or staggered in rows around the cylinder. Persons skilled in the art will appreciate that the workspace may not be provide din a cylinder but in any shape that provides a workspace (e.g., inside a cube, rectangular, triangular, or any other type of housing).

UV-C reflective material may be provided on the flexible printed circuit board around the UVC-LEDs or selectively provided, around the UV-C LEDs placement so as to not generally impede UV-C emanating from the UV-C LEDs, on the interior surface or exterior surface of the cylindrical housing. Such a UV-C reflective material may include, for example, aluminum.

One or more heat sinks may be provided around the UV-C LEDs in order to capture and expel heat from UV-C LEDs away from those UV-C LEDs. A battery and/or wall plug and/or battery and wall-plug may be utilized to charge, for example, one or more rechargeable batteries located inside a housing that includes the working space.

Manual inputs may be operable to receive manual input from outside of a housing that may include the working area (e.g., a UV-C transparent cylinder) or be placed within the proximity of a working area. Temperature, humidity, and flow rate may be added and utilized to, for example, control the intensity of one or more of the UV-C LEDs so that, for example, the intensity may be changed for different temperatures, flows, and/or humidity.

Persons skilled in the art will appreciate that other types of Ultraviolet LEDs, or other light sources, may be provided on an LED array such as UV-B and UV-A LEDs. Similarly, additional wavelengths of light may be provided in LEDs, or other types of light sources. A spectrometer, or other device, may be included to determine the type of material in the working space and may activate different LEDs or different types of LEDs (e.g., based on the detected material(s)). Similarly, different UV-C LEDs, or non-LED UV-C sources, may provide different wavelengths and different modes may be provided to control the UV-C LEDs so a subset of the UV-C LEDs may provide a particular nanometer wavelength (e.g., 255 to 265 nanometers) and other UV-C LEDs may provide another particular nanometer wavelength (e.g., 270 to 280 nanometers).

A flexible circuit board does not have to be rolled, for example, for the flexible circuit board to sterilize a working surface. A device may have a generally flat flexible circuit board at a perimeter separated from a surface that has contaminant (e.g., virus and/or bacteria) that requires sterilization). The housing may have a handle (e.g., a removable handle) so that the UV-C sterilization device can be provided as want for moving over, and sterilizing, a surface.

The housing may include multiple mateable ports for handles such that, for example, one handle may be inserted into one mateable port to provide a sanitizing and a larger handle may be inserted into a different mateable port to provide a sanitizing mop/broom. Such a UV-C sanitizing device may be wall mounted such that, for example, someone can place their hands in a working space and have the hands sterilized. The device may operate on two modes—human mode and non-human mode. The device can prompt this to the user for the mode, wait for the user to activate the mode, or autonomously activate the mode.

The flexible circuit board with multiple UV-C LEDs may be articulated via motors and/or other controls so that different areas that, for example, include UV-C LEDs may be moved away from each other or to each other or moved closer to, or further away from, the other LED's.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows device 100 that may include any number of ultraviolet C (UV-C) light sources such as UV-C light emitting diodes 102 and 103. UV-C sources may have a wavelength between approximately 200 nanometers and 280 nanometers. Processor 106 and additional circuitry 107 may be included on circuit board 101 in additional to input/output ports 104 and 105.

Printed circuit board 101 may be, for example, a non-flexible or a flexible printed circuit board. Input/output ports 104 and 105 may be, for example, contacts to couple to another circuit board or an external device. Processor 106 may, for example, control UV-C LEDs 102 and 103 using firmware that is downloaded into processor 106 or provided in a memory of processor 106 before or after placement on circuit board 101. Persons skilled in the art will appreciate that printed circuit board 101 may be multiple printed circuit boards that are communicatively coupled together to form a multiple circuit board device. Different circuit boards of a multiple circuit board device may be provided in a single housing or in different housings. A housing may be fabricated in multiple parts and adhered permanently or may be removable. Parts of a housing may be coupled by hinges, screws, glue, molding, ultrasonic bonding and/or any other method. A housing may provide an air tight seal.

Firmware updates may be downloaded through input/output ports 104 and 105. Any number of input/output ports may be provided and different protocols may be utilized for different ports. Additionally, blue-tooth (e.g., BLE), contactless (e.g., RFID), telecommunications (e.g., cellular such as 4G or 5G cellular), infrared, or other wireless communication structures may be provided such as wireless communication chips, circuitry, protocols, and ports may be provided. Wireless power generation may be provided and may be utilized by power circuitry to change a battery coupled to printed circuit board 101 (e.g., through battery contact pads on circuit board 101).

Printed circuit board 101 may be a flexible polyimide or flexible Fr4. Persons skilled in the art will appreciate that such a flexible printed circuit board may be, for example between two thousandths of an inch and seven (7) thousands of an inch in thickness (e.g., between two thousandths of an inch and three thousands of an inch in thickness). Silicon chips may be ground and polished before placement on printed circuit board 101 to between, for example, five thousandths and ten thousandths of an inch in thickness). Such chips may be mounted on printed circuit board 1010 via a flip-on-flex structure or via a wire-bonded structure. A wire-bonded structure may be for example a low-provide wire-bonded structure with wire-bonds that are placed with less than a five thousandths of an inch profile above the silicon chip and encapsulant that is less than three thousandths of an inch above each wire-bond. The entire thickness from the bottom of flexible circuit board to the top of an encapsulant of a chip may be, for example under fourteen thousandths of an inch thick (e.g., under twelve thousandths of an inch thick). For example, the thickness from the bottom of circuit board 101 to the top of the encapsulant may be between ten and sixteen thousandths of an inch thick (e.g., between twelve and fourteen thousandths of an inch thick). Wire-bonds may be for example, gold wire-bonds or aluminum wire-bonds. A low-profile encapsulant may be provided that utilizes at least two separate encapsulate provisioning steps in order to provide the low-profile encapsulant.

Processor 106 may be one or more processors and may be provided between, for example, twenty megahertz and five gigahertz. Persons skilled in the art will appreciate that faster processors may provide faster control of UV-C LEDs 102 and 103. Faster control of UV-C LEDs may provide shorter ON times which may provide the ability to damage and sterilize certain elements (e.g., virus) without damaging and sterilizing other elements (e.g., living tissue and cells). Processor 106 may, for example, provide ON times for UV-C LEDs 102 and 103 less than, for example, 100 nanoseconds, less than 10 nanoseconds, less than 1 nanosecond. For example, Processor 106 may turn ON UV-C LEDs 102 and 103 between approximately 1 and 100 nanoseconds (e.g., between 20 and 60 nanoseconds or between 30 and 50 nanoseconds). High speed control circuitry may also be provided in order to control UV-C LEDS 102 and 103 between 1 and 100 femtosecond (e.g., between 1 and 50 femtoseconds or between 1 and 20 femtoseconds).

Circuitry 107 and 108 may include, for example, regulation and control circuitry for UV-C, or other, sources of light on circuit board 101 as well as sources of light and other circuitry on other boards or external devices. Persons skilled in the art will appreciate that UV-C LEDs on circuit board 101 may be, for example, individually regulated and controlled or controlled as a group or in subsets. For example, circuit board 101 may include over ten (10) or over one hundred (100) UV-C LEDs. UV-C LEDs may be regulated and controlled in groups of two or more (e.g., three or more). A portion of UV-C LEDs may be regulated and controlled independently while another portion of UV-C LEDs may be regulated as a group or in sub-groups.

UV-C LEDs on printed circuit board 101 may be, for example, UV-C LEDs having the same wavelength of may have different wavelengths and they may be independently controlled at different times using different control profiles that provide different turn ON an turn OFF pulses (e.g., the duration of an OFF state for one or more UV-C LEDs may be the same duration or a different duration such as a longer or shorter duration than the ON duration for the respective one or more UV-C LEDs). The UV-C LEDs may all be between approximately 200 and 280 nanometers (e.g., provided at or between 250 and 270 nanometers such as provided at or between 255 and 265 nanometers). Some UV-C LEDs may be provided, for example, at or between 250 and 260 nanometers while others are provided, for example, at or between 260 and 270 nanometers. One or more additional light sources may be provided on board 101 such as, for example, UV-B, UV-A, VUV, and visible spectrum light sources.

Visible spectrum light sources may be provided, for example, to provide a visual indicator when board 101 is ON or OFF as well as different operating modes. For example, a visible spectrum LED may be a single-color LED (e.g., white, green, blue, Or red) or a multiple color LED and may provide indication of when a battery (e.g., a rechargeable battery) is low and/or critically low on power. Manual inputs may be included on circuit board 101 to receive, for example, manual input to turn circuit board 101 ON, Off, and/or change between different modes of operation (e.g., different intensities for UV-C LEDs 102 and 103).

Circuit board 101 may be a single layer or multiple layer circuit board. For example, circuit board 101 may have two, three, four, or more layers. Printed circuit board 101 may be flexible. Persons skilled in the art will appreciate that a flexible circuit board may be at least partially or fully wrapped around or contorted around one or more objects (e.g., one or more working spaces for sterilization by the UV-C LEDs of board 101). Persons skilled in the art will appreciate that flexible circuit board 101 may utilized for multiple sterilization devices as flexible circuit board 101 may be able to flex around one or more objects (e.g., one or more hollow cylinders in which working material may be sterilized by UV-C LEDs) or may not be flexed and may lie flat next to an object (e.g., a surface of an object desired to be sterilized). Flexible circuit board 101 may be actuated so it can be flexed around different objects or placed next to an object so one device may be used in different configurations to change the location of elements of circuit board 101 to sterilize different objects and/or surfaces.

Circuit board 101 may include multiple rows and columns of UV-C LEDs and each UV-C LED, row of UV-C LEDs, and/or column of UV-C LEDs may be, for example, independently controlled (e.g., by processor 106 via additional circuitry such as additional circuitry 107). Circuit board 101 may include, for example, rows of three (or more) UV-C LEDs and columns of five (or more) UV-C LEDs). Persons skilled in the art will appreciate that rows may include the same number of UV-C LEDs or a different number of UV-C LEDs than other rows. Persons skilled in the art will appreciate that columns of UV-C LEDs may include the same or different number of UV-C LEDs than other columns. A row of UV-C LEDs may have, for example, six UV-C LEDs so that if circuit board 101 is rolled around a tube in a particular manner that the UV-C LED row provides a hexagonal disc around that tube. Each column may then, for example, provide another hexagonal disc of UV-C LEDs.

Persons skilled in the art will appreciate that circuit board 101 may be folded to provided UV-C LEDs facing in two (or more directions), left unfolded so the UV-C LEDs face in a single direction, wrapped around an object so the UV-C LEDs face into the object, folded inside of an object (e.g., a tube) so the UV-C LEDs face outside of the object, wrapped around an object (e.g., a brontoscopy or proble) with the UV-C LEDs facing away from that object, or in any form to provide UV-C LED light to any object or objects. Persons skilled in the art will appreciate that circuit board 101 may have UV-C LEDs on a single side of board 101 or multiple sides of board 101.

Cross section 110 shows a cross-section of flexible circuit board 113 including UV-C LEDs 114 and 115 inside of a tube having an interior surface 112 and an exterior surface 111. Such a tube may be cylindrical in shape or may have a non-cylindrical shape. Any UV-C material utilized with a sterilization device may be UV-C transparent and may have UV-C transparency greater than fifty percent (50%), greater than seventy percent (e.g., 70%), greater than eighty percent (80%), or greater than ninety percent (e.g., 90%). Such a UV-C transparent material may be, for example, quartz. Cross section 110 may, for example, include a cross section that includes two or more UV-C LEDs such as three or more UV-C LEDS or six or more UV-C LEDs. Persons skilled in the art will appreciate that cross-section 110 may be provided such that a flexible circuit board having UV-C LEDs is inserted into a rigid or flexible tube that is UV-C transparent to be placed in a cavity of a living organism (e.g., a nasal, throat, or lung cavity) in order to sterilize material placed about the tube having outer surface 111 and inner surface 112 from contaminants (e.g., viruses). Persons skilled in the art will appreciate that a thinner thickness between inner surface 111 and 112 of any tube used in connection with a sterilization device may provide more UV-C light to penetrate through inner wall 11 and 112 to interact with a working material. Accordingly, the thickness between inner surface 111 and 112 may be, for example, at or between half a millimeter and four millimeters (e.g., at or between half a millimeter and two and a half millimeters such as at or between a millimeter and two millimeters). For example, the thickness of a UV-C transparent material may be approximately two millimeters in thickness.

Side view 140 shows a side view of a cylinder with a flexible circuit board having UV-C LEDs wrapped around the cylinder. More particularly, side view 140 includes flexible circuit board 141 wrapped around a cylinder that has multiple UV-C LEDs such as UV-C LEDS 142, 143, 144, and 145. UV-C LEDs and 143 may be part of a UV-C disc that includes three or more UV-C LEDs. For example, the far side (not shown) of side view 140 may include a single UV-C LED aligned with UV-C LED 142 and 143 to provide a three UV-C LED disc around a hallow cylinder when placed around a hollow cylinder. UV-C LEDs may be facing into the hollow cylinder to provide UV-C light into a working area inside of the hollow cylinder in order to interact (e.g., sterilize) material (e.g., virus) in and/or moving through that working area. UV-C LED 142 may be aligned with UV-C LED 144 and UV-C LED 143 (and other UV-C LEDs) may be aligned with 145 (and other UV-C LEDs), respectively, so that the UV-C LEDs of multiple discs and/or rows are aligned with each other when wrapped around an object.

Cross-sectional view 120 shows circuit board 123 that may include one more UV-C LEDs (e.g., UV-C LED 124) located around a UV-C transparent hollow cylinder provided by interior wall 121 and exterior wall 122.\

Cross-sectional view 130 shows circuit board 131 located around a hollow cylinder that included an interior wall 132 and an exterior wall 133. Circuit board 131 may have one or more UV-C LEDs (e.g., UV-C LEDs 134 and 135).

Side view 150 shows flexible circuit board 152 wrapped around a hollow cylinder such that LED discs are formed that are staggered from one another. For example, UV-C LED 153 may be associated with two ore more UV-C LEDs located on the far side of the cylinder while UV-C LEDs 152 and 154 may be associated with one or more UV-C LEDs located on the far side of the cylinder. Each UV-C LED disc may have the same (or different) number of UV-C LEDs but, for example, these UV-C LED discs may be staggered such that material flowing through the cylinder at different locations may have staggered UV-C LEDs that may be closer to the material than if the UV-C LEDs were not staggered with respect to one another. Persons skilled in the art will appreciate that multiple UV-C discus, rows, or columns may be staggered in two or more configurations (e.g., three or more configurations) and multiple groups of UV-C LEDs may be staggered differently than different groups of UV-C LEDS.

Device 160 shows a stepped hollow cylinder 162 that has three circuit boards, each having multiple UV-C LEDs wrapped around different portions of the stepped hollow cylinder. For example, circuit boards (e.g., circuit board 101 of FIG. 1) may be placed (e.g., wrapped around) portions 162, 163, and 164. Persons skilled in the art will appreciate that multiple circuit boards (e.g., circuit board 101 of FIG. 1) may be independently controlled via the same of different firmware on each board. Multiple circuit boards may be coupled to a processor and/or circuit board located outside of the boards with UV-C LEDs. A circuit board with UV-C LEDs may act as a master control circuit board to another circuit board with UV-C LEDs that acts as a slave circuit board such that the master control circuit board controls the slave circuit board.

Cross-sectional view 170 includes circuit board 173 around a hollow cylinder including interior wall 171 and exterior wall 172. The cylinder, as in any structure that is provided to include a working space in that structure, may be UV-C transparent. Circuit board 173 may include one or more UV-C LEDs (e.g., UV-C LED 176) that faces into the walls 171 and 172 such that UV-C light from UV-C LED 176 passes through walls 172 and 172 to impact the working space provided by wall 171. A material, e.g. air, may be flowed through the working space provided by wall 171 so that UV-C LEDs may impact (e.g., sterilize) that material from contaminants (e.g., virus and/or bacteria). Persons skilled in the art will appreciate that a flexible circuit board having UV-C LEDs may be laminated into the hollow cylinder itself (e.g., between walls 171 and 172. Such a configuration may, for example, provide UV-C LEDs closer to the working space. A fan, or other material movement system, may be provided to impact the speed that material is moving through the working space.

Post 175 may be UV-C transparent and may include UV-C LED 174. Configuration 181 may be provided in place of UV-C 174 and may include multiple UV-C LEDs. Any UV-C LED may be tilted at an angle on any axis in order to provide UV-C LED light in any direction. UV-C LEDs 182, 183, 184 may be provided on structure 185 and may be tilted differently on one or more axis from each other).

UV-C LEDs 174 or any UV-C LED located outside of a circuit board (e.g. circuit board 173) may be communicatively coupled (e.g., coupled by a physical conductor) to circuit board 173 so that circuit board 173 may control one or more UV-C LEDs located outside of circuit board 173.

A working space may be any working space in any device such as a ventilator device. In providing UV-C sterilization in a ventilator device any air flowing through that ventilator device (e.g., air entering, flowing through, or exiting) the device may be sterilized.

FIG. 2 shows device 200 that may include housing 213. A hollow cylinder may be fluidically coupled to mateable portion 217 and mateable portion 218 so that a working substance (e.g., air in a ventilator) may pass through mateable portion 217, through the cylinder, and through mateable portion 218. Mateable portion 217 may be a male mateable part that fits into female mateable part (e.g., mateable part 218 may be a female mateable part). In doing so, tubing used in, for example, medical devices such as ventiators may be coupled to mateable portion 217 and 218 such that a working substance flowing through the ventilator is temporarily redirected through device 210. Circuit board 219 may include UV-C LEDs (e.g. UV-C LEDs 220, 221, and 222) around a cylinder that circuit board 2019 is wrapped around). One or more heat sinks (e.g., heat sinks 216 and 223) may be wrapped around a portion or all of circuit board 219 to draw heat generated from circuitry and UV-C LEDs away from the working space (e.g., the space inside of the cylinder). The cylinder may be a UV-C transparent material (e.g., quartz) and may include a thickness between an inner wall and an outer wall between approximately 1.5 millimeters and 2.5 millimeters (e.g., approximately 2 millimeters). Persons skilled in the art will appreciate that heat sink 210 and 223 may be a single heat sink wrapped around circuit board 219 wrapped around a hollow cylinder (or other structure providing a working space). Persons skilled in the art will appreciate that a cylinder or other structure may not be provided and circuit board 219 may define the working space itself. For example, circuit board 2019 may be wrapped into a cylinder and a working material may be followed through that cylinder. A protective layer may be placed (e.g., sprayed or placed) on one or more portions of one or more surfaces of the circuit board to provide protection for the circuit board from any working material.

Device 210 may include one or more batteries 215 and 224. Persons skilled in the art will appreciate that batteries 215 and 224 may be separate batteries or a single battery wrapped around housing 213. Batteries may be rechargeable or permanent and removable and replaceable. Charging circuitry may be provided. External power may recharge the power or, for example, may power circuitry of device 210 directly. Switching and regulation circuitry may control, for example, when external power (e.g., wall power) is utilized to charge a rechargeable battery and/or power circuitry of device 210 directly. Manual interfaces 211 may be included such as, for example, to turn device 210 ON/OFF and or change modes or enter other input data into device 210 (e.g., configure device settings and or device modes). Visual indicators 212 may be a bi-stable or non bi-stable display and/or single-color light source(s) and/or multiple color light source(s). A visual indicator may be a two-color display (e.g., black and white or two tone display) or a several color display (e.g., a color display) and may include an interface for the consumer. Visual indicators 212 may include the status of device 210 Status may include, for example, status information such as, for example, whether device 210 is operating properly or incorrectly as well as data associated with the device. For example, device 210 may provide a visual indication of a low battery, broken part (e.g., broken UV-C LED). Audio indicators may also be provided such as speakers.

Device 1350 may include a five-sided structure ((e.g., structure 1352) and may include LEDs 1351, 1353, 1356, 1358, and 1359, which may be, for example, facing inside of structure 1352 so that UV-C light is provided into structure 1352. UV-C LEDs 1354, 1355, 1357, and additional UV-C LEDs may be positioned inside of a working substance channel and may be provided providing UV-C light toward structure 1352. Reflective material may be placed on the interior (or exterior of structure 1352. For example, structure 1352 may be a UV-C transparent material that includes a printed circuit board with UV-C LEDs wrapped around structure 1352 and a UV-C reflective material may be provided so that UV-C light trying to escape structure 1352 is reflected back into structure 1352. The UV-C reflective material may not be provided, for example, around LEDs or sensors for sensing attributes inside of structure 1352.

Persons skilled in the art will appreciate that structure 1352 may be a six sided, or more structure (e.g., a printed circuit board). The printed circuit board may a flexible circuit board that is flexed around a cylindrical tube to create a six sided structure. A disc of three UV-C LEDs may be provided with a one side space between each of the three UV-C LEDs. Each column of UV-C LEDs may have, for example, three UV-C LEDs and may stagger so that as the LED discs are provided down a UV-C transparent structure (e.g., a UV-C transparent cylinder) the location of the UV-C LEDs rotate positions. For example the three UV-C LED disc located around the cylinder tube may be in a two configurations where the first configuration has three UV-C LED locations and three locations without UV-C LEDS and then the second configuration may have UV-C LED locations where these spaces occur and may have non UV-C locations where the previous configurations UV-C LEDs occurred. A cylindrical tube may have, for example, five or more (e.g., six) UV-C LED discs where each UV-C LED disc has three or more UV-C LEDs. A three UV-C LED disk repeated 5 times (e.g., in one or more disc configurations) provides fifteen UV-C LEDS providing UV-C light into the UV-C transparent cylinder. Persons skilled in the art will appreciate the diameter of a cylindrical tube may be for example, a diameter that is less than a diameter of a bacterial/particulate filter without decreasing working substance flow like a bacterial/particulate filter as the UV-C light may not provide resistance on the same amount as a physical particulate and/or bacterial filter. A diameter of the inner diameter of a cylinder may be, for example at or between 2 millimeters and 25 millimeters such as at or between 5 and 20 millimeters, such as at or between 12 and 17 millimeters such as at or between 14 and 16 millimeters (e.g., approximately 15 millimeters). An outer diameter may extend between, for example, one half and three millimeters past an inner diameter (e.g. approximately 2 millimeters for a thickness of 2 millimeters). UV-C LEDs may be for example, approximately at or between 255 and 270 nanometers (e.g., approximately 260 or approximately 265 nanometers). Persons skilled in the art will appreciate that the components of a UV-C generating device may be of any size or shape. For example, a cylinder may be, for example, over 25 millimeters and under one half of a millimeter in inner diameter.

Device 1360 may include structure 1361 and may include UVC array 1362 and UVC array 1365. UVC array 1362 may include, for example, UV-C LEDS 1363 and 1365. UV-C array 1362 may be about a first UV-transparent tube and UV-C array 1365 may be about a different UV-C transparent tube.

Persons skilled in the art will appreciate that a structure defining a working space (e.g., a cylinder) may have UV-C LEDs on one side of the structure and a portion of that structure may be UV-C transparent while another portion of the structure may be non UV-C transparent (e.g., UV-C absorbent or blocking) and may include a reflective surface on the non UV-C transparent material to reflect UV-C light back into the working area. In doing so, for example, UV-C LEDs may be placed about the UV-C transparent areas but not the UVC non-transparent areas. In doing so, for example, one or more UVC-LEDs may be able to provide a UV-C sterilization capability in a tube without having to provide UV-C LEDs about multiple sides of the tube. The UV-C LEDs may be provided on one or more dies but not provided on one or more sides. UV-C reflective material may be provided in order to, for example, increase the amount of UV-C light that is retained in the working area.

Structure 1370 is provided that includes portion 1371, 1372, 1373 that has a different interior working substance shape. UV-C LEDs may be positioned across portions 1371, 1372, and 1373 (e.g., UV-C LEDs 1374-1377 positioned around portion 1372).

FIG. 14 shows device 1400 that may include flexible circuit board 1403 that may include UV-C LEDS 1401, 1402, and 1403. Each UV-C LEDs 1401, 1402, and 403 may be included on independent circuit boards or mounted independently to a structure. Structures 1405, 1408, 1406, 1409, 1407, and 1410 may each provide one or more axis of movement so that one or more UV-C LEDs attached to the structures may be moved with the structure.

FIG. 15 includes device 1500 that may include UV-C generating device 1511 powered and/or controlled and/or communicate data between USB port 1512. In doing so, for example, UV-C generating device 1511 may be coupled to a computer (e.g., a laptop computer) as well as other devices (e.g. a vehicle such as an automobile).

Persons skilled in the art in possession of the present disclosure will appreciate any device (e.g., any UV-C generating device) may be added to a different device or made integral with the device, for example, integrated with a ventilator fan pump and information from UV-C sensors may be used to drive or control the UV-C generator.
